I started working on the daunting task of liquid textures. The working document at the top shows roughly how I got to these magma tiles through several generations, starting in the centre and just moving out as I decide to start a new idea.
I always struggle with liquids because their lighting rules are generally complicated in comparison with solids. Magma seemed doubly daunting because it emits its own light. I wanted to give some sense of cooler patches that had partially solidified as well. I think I got a pretty good result.
Below are a couple quick mockups that I just banged together. The top image is just a raw composition, and the mockup at the bottom has the terrain shader roughly blended over the magma. I’ll be doing more work to get the masking and shading to look right.
